Specification of l lietters Patent.

Patented Aug. 13,1912.

Application filed December 14, 1909. Serial No. 533,045.

To all whomz't may concern .Be 1t known that we, PHILIPPE AUeUsTn Gun:and CHARLES EUGENE Gum, citizens of the Republic of Switzerland,residing at Geneva, Switzerland, have invented new and useful Imrovements in Apparatus for Producing Enc othermic Reactions in Gases, ofwhich the following is a specification.

This invention relates to improvements in apparatus for submitting gasesto a very high temperature for producing therein endothermic reaction.

One important use of the apparatus is the oxidation of atmosphericnitrogen, obtained by passing through the apparatus a current of air ora mixture of nitrogen and oxygen.

The invention resides in the apparatus hereinafter described andillustrated in the drawing.

That which is regarded as new is set forth in the claims.

In the said drawing, Figure 1 is a vertical sectional view of theapparatus. Fig. 2, a diagrammatic view of an installation in which thegases are moved through the apparatus by suction. Fig. 3, a similar viewin which the gases are forced through th apparatus. Fig. 4:, a detailshowing an arrangement for preliminary heating of the cooling the tubes.Fig. 7, a detail of the electrodes. Figs. 8, 9, details showing meansfor cooling the electrodes.

The apparatus comprises a plurality of vertical tubes 1, circular or ofother suitable crosssection, which constitute the furnaces in which thereactions take place, and which open at their upper ends into acollectingchamber 2, common to the several tubes. At the lower end ofeach of the tubes, and preferably with their heads disposed slightlywithin the tubes, are pairs of electrodes 3,

. arranged vertically, parallel to each other,

and in electrical tension or under electrical potential. The electrodesare insulated from each other; as shown they are mounted on a base 4 ofinsulating material and connected in series. The gases to be subjectedto the action of the arcsentenat the lower ends of the tubes and passupwardly therethrough in as many parallel currents as there are tubesand may be caused to move by-the suction of a pump, shown conventionallyat 6, in the diagrammatic illustration, Fig. 2, in communication with aconduitleading from the collection-chamber the intensity of the aircurrents. v ustment of the electrodes toward each other nitrogenthelower ends of the tubes may 7 conveniently be open to the atmosphereand the latter caused to move through the tubes by suction. Obviously,however, the atmospheric-air or gases may be moved by a force pump 8, asdiagrammatically shown in Fig. 3, in which case the lower ends of thetubes communicate with a distributing trunk 9. i

If it is desired to preliminarily heat the gases they may, as shown inFig. i, be caused to pass through jackets l0 surroundmg the tubes beforepassing into the latter. If 1t is desired to keep the tubes cool, watermay be circulated through appropriate vessels 11, as shown in Figs. 5,(i. The electrodes, also, may, if desired, be cooled bv a circulation ofwater, as in Figs. 8, 9. i

It is convenient and suitable to construct the apparatus on the basis of100 kilowatt units at least.

In operation the arcs which form between the heads of the several pairsof electrodes develop, under the influence of the currents of gasespassing through the tubes, into an elongated, inverted V-shape, asshown, and the degree of elongation varies according to No adtocompensate for wear while the apparatus is in use is necessary, becausewith the described parallel arrangement of the electrodes the distancebetween the heads of the electrodes is not increased as the latter wearaway in use.

As shown in Fig. 7 of the drawing, the

heads 12 of the electrodes may be separable from the stems l3 andconnected thereto in any suitable way, as by, a pin and socketconnection. This arrangement is desirable as it enables ready renewal ofthe electrode heads. I

Having thus described the invention, what is claimed is 1. Apparatus forthe production of endothermic reactions on gases comprising aplurality-of vertical tubes, a collecting chamber with which the upperends of the tubes comnuinicate, pairs of vertical electrodes arranged atthe lower end of each tube and connected electrically in series, the gasto be treated being divided into as many parallel currents as there aretubes.

Apparatus for the production of endothermic reactions ongases comprisinga plurality of vertical tubes, a-collecting chamvertical tube, and apair of vertically ar ranged, parallel electrodes at the lower endthereof.

4-; Apparatus for the production of endothermic reactions on gases,comprising a plurality of vertical tubes, a collecting chamber .Withwhich the upper ends of the tubes communicate, pairs of verticalelectrodes arranged at the lower end of each tube and connectedelectrically 1n series, and means in connnunicatlon with the respectivetubes and through which the glass to be treated passes for preliminarilyeatin the gases to be treated before entering t'e vertical tubes. 7

5. Apparatus for the production of endo- 'thermic reactions on gases,comprising a plurality. of vertical tubes, a collecting chamber withwhich the upperends of the tubes communicate, airs of vertical elecsotrodes arranged at t e lower end of each tube and connected electricallyin series, anti means for cooling said tubes.

In testimony whereof We have hereunto set our hands in presence of twosubscribing witnesses.
